SS preamps with two XLR inputs and at least four outputs [two of them XLR]

The OP is looking for "at least four outputs". I personally haven’t seen any preamps, maybe except for home theatre processors, that meets that requirement. I think most of models recommended don’t either.
Using splitters is an option. Or check the miniDSP thread.

I'm the OP---- re kalali's apt comment: Many of the preamps suggested do not have 4 sets of outputs. 
kalali is correct: that configuration is indeed rare. My  PS Audio PCA-2 does have two pairs of XLR and two pairs of RCA outputs, which I use to drive two main amps [separately] and two pairs of sub-amps. However, it does not have two pairs of XLR inputs, but only one.... thus my search.
In any event, thanks for all the suggestions.... they are much appreciated. 

@kalali
two XLR (input or output )
Does it mean  1 left and 1 right
or  2 X (1 left +1 right)  ?

I meant 4 pairs of outputs.... 2 pairs XLR, 2 pairs RCA, i.e. the configuration on my current PS Audio PCA-2.... What I want to add to my system is a preamp with at least two pairs of XLR inputs, so that I can drive a Denafrips Pontus and an Oppo Sonica via their XLR outputs.
Again, thanks for all the suggestions.

Must it be SS? If not, check with Ralph, username atmasphere, who is a manufacturer who frequents this site. His Atma-Sphere MP-3 almost gets you there. I Know he can add another XLR output, but I don't know if he can add two additional RCA outputs along with it
